Bench testing of voltage, ohms and
amps made easy and precise
• AC and dc voltage, current, resistance
and diode test
• High accuracy, basic V dc 0.03 %
• 2A fused and 20A range
• Easy-to-read, 0.5 Inch LED Display
This 4 1⁄2 digit (20,000 counts) digital
multimeter features True RMS (ac or
ac+dc coupling) measurement capabilities to assure accuracy regardless of the
types of waveforms. The BDM40 features
high resolution at a low cost, which makes
it ideal for production test, QA test, depot
service and university and school labs.
Measurement capabilities include
voltage from 10 mV to 1200 V dc and to
1000 V ac, current from 10 mA to 20 A,
and resistance from 10 mΩ to 20 MΩ.
Diode test is provided on the 2 kΩ range.
The interlocking push buttons on the
front panel provide easy selection of functions and ranges. Bold labels on the input
jacks increase visibility and offer an added
safety, as does the fully fused 2A jack.
The BDM40’s full 360° adjustable tilt
bail and LED display maximize readability
for most any bench application. Each
meter comes with standard test leads,
power cord, and operator’s manual. A full
line of optional probes, current clamps
and test leads is available to meet your
application needs.
